Air Distribution for Cement & Powder Silos
（Katup Distribusi Udara untuk Silo Semen & Serbuk）
High-performance air distribution valve for uniform aeration of cement, fly ash, and powder silos
Overview
A silo bottom air distributor is designed to evenly distribute compressed air from a single inlet to multiple aeration pads, air slides, or fluidizing boxes installed beneath a silo cone. By ensuring balanced airflow to each aeration zone, it helps prevent material arching, rat-holing, and dead zones commonly found in cement and fly ash silos.
This air distribution valve is widely used in cement silo aeration systems, fly ash storage silos, powder discharge systems, and bulk material handling installations where stable, dust-free material flow is essential for continuous operation.

Technical Specifications
Applicable Materials and System Scope
Silo bottom air distributors are designed for fine powders that require controlled fluidization, such as cement, fly ash, limestone powder, and mineral dust. They are not intended for coarse aggregates, which typically rely on mechanical discharge methods rather than aeration-based systems.
Advantages
✅ Prevents dust leakage and material blockage
✅ Improves silo discharge efficiency
✅ Reduces maintenance and downtime
✅ Ensures stable and uniform aeration
✅ Works with multiple aeration pads or air slides
✅ Long service life in harsh industrial conditions
Uniform air distribution is critical to effective silo aeration, as uneven airflow often leads to localized blockage and unstable discharge.

FAQs About Silo Bottom Air Distributors
What is a silo bottom air distributor used for?
A silo bottom air distributor is used to distribute compressed air evenly to multiple aeration pads or air slides at the bottom of a silo, ensuring smooth powder discharge and preventing material blockages.
Which materials can this air distributor handle?
It is suitable for cement, fly ash, limestone powder, mineral dust, and other fine bulk materials.
Can the number of outlets be customized?
Yes. Outlet numbers, diameters, and flange standards can be customized according to your silo design and airflow requirements.
What air pressure is required for operation?
Typical working pressure ranges from 0.3 to 0.8 MPa, depending on material properties and silo size.
Is this air distributor compatible with air slide conveyors?
Yes. It is commonly used together with air slide conveyors for efficient powder transport.
What is the difference between a silo bottom air distributor and an aeration pad?
An aeration pad is a local fluidizing device installed inside a silo cone, while a silo bottom air distributor is a centralized valve that distributes compressed air evenly to multiple aeration pads or air slides, ensuring balanced and stable aeration across the entire discharge area.
